of Hawaii in the southern North Pacific. HAZWRAP was tasked to devise a scheme for disposal of polychlorinated biphenyl (PCB) -contaminated transformer fluids. Alternatives to incineration were sought because of the remote location, harsh marine environment, and difficult logistics in transporting PCB-contaminated materials to the United States for disposal. Many of the transformers on Kwajalein Island contain askarels in the range of 300,000- to 700,000-ppm PCB. A surgery of PCB disposal methods identified thermal destruction as the only available and permitted process for destroying very high-concentration PCB fluids. The economics and risk associated with transportation make this option unattractive. Existing chemical destructive methods are permitted for <10,000-ppm PCB and result in incomplete degradation of PCB. A new chemical method referred to as base catalyzed destruction (BCD) was developed by scientists at the Environmental Protection Agency Reduction Engineering Laboratory. The BCD chemical reaction will destroy PCBs in excess of 100,000 ppm. This emerging technology was not at the process or demonstration phase of development. HAZWRAP tasked scientists and engineers from Oak Ridge National Laboratory to develop and scale up the process. These efforts will result in a mobile chemical reactor unit that can be transported to remote locations and decontaminate high-concentration PCB fluids on-site.

ISSN: DEN 0170-6977 (Federal Republic - Germany Country of Publication: Germany LSeoos Abstract: Results of radiation exposed persons from the population are presented and the consequences are valuated. The radioecological burden and the consequences of events for the environmental medicine are debatted (e.g. Hiroshima/Nagasaki 1945, Bikini H-bomb experiment 1954, container explosion in the MAJAK nuclear weapons centre 1957 and inadmissible waste removal in south Ural 1950/51, accident at the Chernobyl power plant and their consequences particulary for Germany 1986 till now, theft of sources used for radiotherapy and the contamination of the environment after the Goiana accident 1987). Further the risk of radon cure, transatlantic flights, vagabondized sources, uranium mining and some cases of probable stochastic radiation effects (e.g. leukemia clusters at Sellafield, Elbmarsch and Sittensen) is discussed.
